Confirmatory Lithium Leaching And Lithium Carbonate Precipitation Test Work from Tonapah Claims

VANCOUVER - American Lithium Corp. reported on confirmatory lithium leaching and lithium carbonate precipitation test work from Tonopah Lithium Claims (TLC) mineralization. This test work supports the maiden Preliminary Economic Assessment (PEA) for the TLC project, which is in final phase of completion and expected to be released shortly.

Highlights: Sulfuric acid leaching TLC claystone mineralization achieved 97.7% lithium extraction with short 2-hour leach time; Overall lithium recovery of at least 88.1% from leach through primary lithium carbonate precipitation including lithium losses of only 4.7% during leachate neutralization, 4.9% during impurity removal and crystallization/washing steps; Calculated Lithium Carbonate (“LC”) purity of 99.4% based on ICP-MS/ICP-OES chemical analyses of TLC primary lithium carbonate product at SGS Lakefield analytical laboratories prior to any additional refining steps; LC product requires an additional process step in the flow-sheet to remove remaining impurities (Potassium – K; Calcium - Ca) and produce battery-grade LC or Lithium Hydroxide; and PEA will reflect work done to date, but process optimization work will continue.

Simon Clarke, CEO, said, “We are very pleased with the latest TLC lithium carbonate precipitation results and on-going optimization leach test work which has achieved very high lithium extraction, high overall lithium recoveries and extremely good lithium purity. This work forms key inputs into the maiden PEA for the TLC project, scheduled for release this month, and enables the completion of flow sheets to produce battery grade lithium carbonate and / or hydroxide. This marks yet another successful milestone for the project and team and capped off a year that saw significant positive achievements and results.”
